Write and solve a MA or efficiency problem

A crate of mass 500kg is raised to a height of 10ft from the floor. What is the GPE (Gravitational Potential Energy) it has acquired with respect to the ground.

What happens to a current when the electric field in the wire increase

72) A coil with a self-inductance of 6.0 H is connected to a dc battery through a switch. As soon as the switch is closed, the rate of change of current is 2.0 A/s. What is the emf induced in this coil at this instant

What kind of fluctuations in weather patterns do you expect to see in your area? Will the fluctuations or changes vary by month, by year, or will they remain fairly consistent?

During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a velocity of 2.60 m/s, grabs and holds onto him so that they move off together with a velocity of 1.30 m/s.

What effect does an increase in temperature have on viscosity?

Aman tosses a jart upward with a velocity of 14.1 m/s a 60° angle

Describe accuracy, precision and best fit line.
